1 lb. Color Changing Nuclear Grade DI Resin. We recommend the color changing resin because it gives you an idea of when to start checking your TDS meter more often.

We vacuum package our resin, this removes virtually all of the carbon dioxide within the packaging itself.

The resin changes from Blue to light brown as it is depleted. The color indicator in DI resin is just a visual indicator of when the resin is close to exhausting and should not be considered and accurate representation of when the resin is fully depleted, it can often be good much longer. We strongly suggest using inline TDS meters to definitively tell you when it is time to change your resin.

Product Specifications

Resintech MBD-30 is a color indicating mixed bed resin. The anion resin is a Type I strongly basic gel resin with an indicator dye that changes
from blue to light brown as the resin exhausts.

ResinTech MBD-30 is designed to provide demineralized water with a resistivity in excess of 10 megohm. It is specially intended for use
in cartridge applications with clear (see-through) housings. Such systems are typically designed without meters and rely on the changing color
of the mixed bed resin to indicate exhaustion. In typical operation, there is a “safety line” at the exit end of the cartridge, and when the color
change reaches that level, the cartridge is considered exhausted and exchanged for a fresh cartridge.

A constant supply of high purity water can be obtained by using two cartridges in series and allowing the first cartridge to completely change
color. During this operation, the second cartridge ensures that the water leaving the system is of the highest purity. New cartridges are placed
into the polishing position and the remaining cartridge is put into the “roughing” position. This ensures complete utilization of all the exchange
capacity, which lowers operating costs while increasing average quality.
